Volatile organic compounds (Volatile Organic Compounds, VOCs) in human breath can be used as breath biomarkers of physical condition. Their composition and concentration may vary depending on human health conditions.

Some metabolites and chemical substances in the body or blood stream can be released when they enter the alveoli through the pulmonary circulation and are discharged from the body through respiratory exchange. Therefore, the concentration of exhaled gas components can reflect the level of certain components in the blood. The measurement of volatile chemical substances in human exhaled gas is a detection technology that does not damage the body.

In the human body, acetone is formed by metabolism or lipolysis leading to ketonization. Therefore, changes in acetone concentration can provide information on important metabolic changes that occur in the body. Acetone is a hallmark gas exhaled by diabetics, and healthy people are about0.3-0.9 ppmPeople with diabetes are generally greater1.8ppmExhaled acetone gas concentration analysis is a screening method for rapid diagnosis of diabetes.

Compared with healthy people, diabetic patients show higher acetone concentrations due to lower insulin levels, and fasting and caloric restriction also cause higher acetone concentrations.

Lipolysis, which occurs after exercise, increases the acetone concentration by approx.200 ppb. Therefore, the purpose of dynamic assessment of human health status can be achieved by dynamic detection of acetone concentration. Moreover, due to individual physiological differences, it is not reasonable to use a specific standard concentration for diagnosis. Only by constantly monitoring the change of acetone concentration can we make a comprehensive judgment on human health status.

Acetone analysis is a non-invasive analysis method that represents the level of blood ketone bodies. It can not only diagnose diabetes, but also is an important detection index of liver fat metabolism. For example, the ketone-raising diet used for diabetes treatment and weight control will obviously increase this index. Aerobic exercise will also increase the liver fat metabolism rate, and the blood and respiratory acetone levels will also increase.

Therefore, an efficient and reliable acetone gas sensor can measure the change of acetone content in human respiratory gas, which is very necessary for the early warning of human health status and non-invasive diagnosis of diseases.
